Smart Drip Irrigation using IOT

Objective

The objective of the project is to over come the current methods of automation in drip irrigation of farms with even more cost and energy efficient system and also more user friendly at live feeds display

Abstract

This system is built to offer farmers, an automation in drip irrigation system. The proposed system uses a solar powered rover with sensors, cloud service, an android app to monitor the field ,control the rover manually as well as to switch the motor on or off for drip services. This system provides the user with real time data of the field. This is done by a WeMos D1 which is attached to the rover and it also alerts the user when there is an overflow of water for a particular plant are area by using the soil moisture sensor which sends the readings to the cloud. Obstacle detection technique is implemented in the rover which helps in sending notification to the user when the rover gets disturbed in its way. By using our system the drip irrigation can be done by the farmer (user) at any time anywhere in an efficient and effective way.

Innovation

  • The map for the farm is prepopulated to the rover for its automatic movement in the farm, it can also be controlled and simulated manually using the android app if there is any change in the movement for next time.
  • The rover is controlled by a solar powered battery in which the solar plate is just fixed at the top of the rover.
  • Digital image processing technique is also used to alert the user when the plants get affected by certain diseases (which changes the color of the leaf or the stem gets broken).
